Struct PendulumScenario 

pub struct PendulumScenario { /* private fields */ }

Simple pendulum scenario.

Implementations

impl PendulumScenario

pub fn new(config: PendulumConfig) -> Self

Create a new pendulum scenario.

pub fn init_state(&self) -> SimState

Initialize simulation state for the pendulum.

The pendulum is modeled as a particle constrained to move on a circle. State is represented in Cartesian coordinates (x, y) where:

• Origin is at pivot point
• y-axis points downward
• Angle is measured from vertical (y-axis)

pub fn create_force_field(&self) -> PendulumForceField

Create force field for pendulum (gravity + tension constraint).

pub fn theoretical_period(&self) -> f64

Get theoretical period (small angle approximation).

pub const fn config(&self) -> &PendulumConfig

Get configuration.

pub fn current_angle(state: &SimState) -> f64

Calculate current angle from state.

pub fn current_angular_velocity(state: &SimState, length: f64) -> f64

Calculate current angular velocity from state.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PendulumScenario

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
